Re: Creating a new kernel recipe for v3.2

Thanks for the tip.

After the modification,

I ran "bitbake virtual/kernel" and now the system is consuming over 50+GB of virtual memory , 15+GB of physical memory & 80% CPU for the command "python bitbake virtual/kernel" and 60% CPU for "scripts/kconfig/conf --oldconfig Kconfig"!!!

The size of OETEMP is over 55GB and growing!

I'm using overo-2011.03 as the base branch and all stock-setting as per gumstix using angstrom-2008

Don't know, haven't gotten around to testing that yet. Are you sure
it is a kernel issue and not a user space issue? Or perhaps a
kernel/user space mismatch?

Have you tried using the iw tools rather than the old (and I think
deprecated) iwconfig tools?

Re: Creating a new kernel recipe for v3.2

Hi dtran11,

As you mentioned they moved to cfg80211/nl80211 (I think. No more wext) back in 2.6.36 kernel. Also 'iwconfig' is no developed (only bugfixes?) and is deprecated. 'iw' changed old 'iwconfig'. I find 'iw' having less features and I am not fully sure what would be the proper way of using it via /etc/network/interfaces.

Because of the changes to libertas driver I have moved to 2.6.34, which is not that nice. Later versions of libertas driver looks more stable.

On newer versions 2.6.39, 3.0, 3.1 I am not able to set encryption for Ad-Hoc network. I had some problems with early 3.2-rc kernels and I was not able to test that due to time constraints.

Your Linux/Mac OS X/Windows machine should report it as private network and require to enter the password during connection to station. Well, I have noticed that if connect to the station, which has encryption set, but still available publicly, my DHCP and other services are not working. It looks like encryption might be working, but during connection procedure I was never asked for the encryption key. I couldn't find a way to set encryption key manually under Mac OS X.

I have tried doing it with iw, but I can not add the key.
iw wlan0 set type ibss
iw wlan0 set channel 4
iw wlan0 ibss join foo-adhoc 2412

Re: Creating a new kernel recipe for v3.2

Hi guys, i have followed all of the above instructions including whatever else i could dig up on the forum to build Steve' version 3.2 with success but i need your wisdom to ensure i have done everything properly. Could you all please have a look at the lines below to ensure i am doing this properly?

# some of the OE provided native tools are a bit buggy
# uncomment the line below if you run into build failures due to the recipes listed below
# you will also need to install your distro's version of these recipes on your build machine
#ASSUME_PROVIDED += "gdk-pixbuf-csource-native imagemagick-native librsvg-native"

--------------------------------------------------------------------
The command like to build the image is:

cd ~/overo-oe
bitbake omap3-console-image

Re: Creating a new kernel recipe for v3.2

Did you get it working?
I'm working with the Sakoman 'omap-3.2' branch and after using the
omap2plus_defconfig and fixing some compile errors in the beagle and
overo board files it compiles without errors. However the system is not
booting with this kernel :(
There's nothing coming after "Uncompressing Linux... done, booting the
kernel.", even after activating early printk's.

Does anybody have a working kernel config for v3.2? I figured out that
the defconfig significantly differs from the defconfig I used to compile
v3.0 (successful compilation & boot).
It's important for me to have the most recent kernel because of some
drivers (IIO & IMU) in the staging folder, which didn't work properly in
v3.0. I'm hoping that the recent patches in this area are fixing the issues.
